g Using calculus and the SDT (then FDT if necessary), find all global and local maximum and minimums given the function f(x) = x

iren [92.7K]

Answer:

$S_{1 } (x,y) = (0.333, 0.815)$ (Absolute minimum) and $S_{2} (x,y) = (-1, 2)$ (Absolute maximum)

Step-by-step explanation:

The critical points are determined with the help of the First Derivative Test:

$f'(x) = 3\cdot x ^{2} +2\cdot x -1$

$3\cdot x^{2} + 2\cdot x - 1 = 0$

The critical points are:

$x_{1} \approx 0.333$ and $x_{2} \approx -1$

The Second Derivative Test offers a criterion to decide whether critical point is an absolute maximum and whether is an absolute minimum:

$f''(x) = 6\cdot x +2$

$f''(x_{1}) = 3.998$ (Absolute minimum)

$f''(x_{2}) = -4$ (Absolute maximum)

The critical points are:

$S_{1 } (x,y) = (0.333, 0.815)$ (Absolute minimum) and $S_{2} (x,y) = (-1, 2)$ (Absolute maximum)

James earns $584 per week. If he receives a pay increase of 7.5%, find:

liberstina [14]

So the pay after the increase is 4380 so subtract 4380-584 which equals 3796.

Sliva [168]

The force for the case 1 is 64 pounds and the distance is 9 feet, it is:

$\begin{gathered} \frac{k}{9^2}=64 \\ k=5184 \end{gathered}$

Now, if the force is 36 pounds, let solve for the distance:

$\begin{gathered} \frac{k}{r^2}=36 \\ \frac{5184}{r^2}=36 \\ r^2=144 \\ r=12 \end{gathered}$

Hence the answer is 12 feet.

Cos (x + π/ 3) + cos (x - π/ 3) = 1 Solve for "x" on the interval [0, 2pi)

kenny6666 [7]

$\bf cos\left( x+\frac{\pi }{3} \right)+cos\left( x-\frac{\pi }{3} \right)=1\\\\
-----------------------------\\\\\
[cos(x)cos\left( \frac{\pi }{3} \right)\underline{-sin(x)sin\left( \frac{\pi }{3} \right)}] 
+ [cos(x)cos\left( \frac{\pi }{3} \right)\underline{+sin(x)sin\left( \frac{\pi }{3} \right)}]=1
\\\\\\$

$\bf cos(x)cos\left( \frac{\pi }{3} \right)+cos(x)cos\left( \frac{\pi }{3} \right)=1\implies 2cos(x)cos\left( \frac{\pi }{3} \right)=1
\\\\\\
2cos(x)\cdot \cfrac{1}{2}=1\implies cos(x)=1\implies \measuredangle x=cos^{-1}(1)
\\\\\\
\measuredangle x = 
\begin{cases}
0\\
2\pi 
\end{cases}$
